SPECTACLE-J OlNT.

SPECIFICATION forming part of Letters Patent No. 361,831, datedApril 26, 1887.

Application filed June 4, 1886. Serial No. 204,149. (No model.)

To aZZ whom it may concern:-

Be it known that I, PAUL MOEWS, of New Castle, in the county of \Vestchester and State of New York, have invented a new and Improved Spectacle-Joint, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved spectacle-joint which gives a fine appearance to the spectacles, is durable, and is easily manufactured.

The invention consists of end pieces, each having a trunnion formed on its face, a temple-disk having a central aperture fitting over the said trunnions, and a screw for holding the parts together and located between the inner ends of the end pieces and'the temple-disk.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. v

Figure l is a plan view of my improvement on an enlarged scale. Fig. 2 is a cross section of the same on the line or m, Fig. 1. an inside face viewof one of the end pieces, and Fig. 4 is a face view of the joint end of the temple.

Heretofore spectaclejoints were provided with end pieces having trunnions,through the center of which passed a screw for holding the end pieces together; but this screw weakened the trunnions to such an extent as to form a very insecure joint.

In my improved joint A,I provide each of the end pieces, B, with the disk 0, on the inner face of which is formed the central trunnion, D, which is flush with the inner face of the end piece, B. The temple E is provided with the usual disk, F, having the central aperture, G, which fits over the trunnions D, formed on the two end pieces, B. The end pieces,B, are provided with the usual offsets, I and J, which form stops for the ends of the usual flange, K, formed on the temple E and partly surrounding the disk F.

'Fig. 3 is The end picces,B,and the temple-disk F are held together by a screw, H, which screws in the end pieces, B, between their ends and the temple-disk F.

It will be seen that when the two end pieces, B, are held a short distance apart the temple disk F can be slipped between the two pieces, so that the aperture G of the disk will pass over the two trunnions D of the end pieces, B, and the faces of the disk F will be in bearing contact with the inner face of each of the disks 0 of the end pieces, B. The latter are then fastened together,in the usual manner,bv means of the screw H. v

It will be seen that,as the screw H does not pass through the trunnions, the latter are not weakened in the least, and thus a very strong joint is made.

The trunnions D, being formed directly on the inner faces of the end pieces, B, save considerable expense in the manufacture, and at the same time they form a durable and reliable bearing for the temple, and as no spindle or pin is visible on the outside the spectaclejoint A has a fine appearance.

Having thus described myin'vention, what I claim as new, and desire to secure by Letters Patent, is

In a spectaclejoint, the end pieces, B, each having a trunnion, D, formed on its face, and the temple-disk F, having a central aperture which fits over the two trunnions D of'the end pieces, in combination with a screw, H, screwing on the end pieces betweenthe inner ends of the pieces B and the temple-disk, and hold- 7 ing the said templedisk in place on the end pieces,B, substantially as and for the purpose described.
